He is still enjoying C++, which has been the only constant in his game-dev career, as he worked in all major game programming teams: gameplay, network, engine, tools, user interface etc.

Working in Ubisoft Romania online team, he now writes client-server code with a focus on performance.

The Compiler is Your Friend: Practical lessons learned from AAA game development

Dec 16, 2021

A fast walk through various problems we encountered while developing AAA games, with a focus on performance optimization, tips & tricks and compilation speed.

In this session, we adapt code from big monolithic code bases, while handling a real-time application with tight performance constraints.

The unique perspective of our game-dev experience will illustrate the practical concepts throughout the presentation, showing how to deal with the complexity of big monolithic code bases. We will look at:

a const case study
compiler optimizations
coding guidelines
clang llvm optimizer examples
code architecture for real-time applications, showcased by a small experiment
a real life scenario where the compiler was our friend.

Throughout the session we discuss what we do at Ubisoft to maintain code quality, fast iteration times and runtime speed when working on big codebases, and we end with a high level presentation of a real life scenario where the compiler was our friend.
